HUNT, M.D. A mtrieum Mutual Llablllta Insurance Company ROBABLY the leader in the pa the discomfort now produced by in P rade of industrial diseases is an acute or chronic inflammation of dustrial dermatitis. the skin which we call dermatitis. TMhisetals disease may present itself in any type of shop, factory or foundry.

Much investigation is under way to determine why one person may be sus ceptible to a certain substance while an other is not. It has been proved many times that a poisonous substance formal within the body has been able to prolong the action started by some external in fluence. A printer developed a marked dermatitis from ink which persisted for two years. Finally food tests were made and showed that be was susceptible to lettuce. Removing this from his diet cleared the skin. He returned to his usual occupation without a return of symptoms. blending gasoline and which is readily absorbed through the skin, having a tendency to create changes in the nerv ous system. The effect of other forms of lead, through that avenue of entrance, is practically nil, which explains the ex tremely low poisoning rate In typeset ters, painters and others who continually come in contact with metallic lead. Lead in any form, introduced through the mouth, acts rather slowly when com pared with the inhalation of lead dust or fumes. However, no matter whit the portal of entry may be, lead is acted upon by the body fluids and so con verted that it may eventually be de posited within the bones. Those bony safe deposit vaults may retain their lead contents for days or for years, and if the exposure is removed, The poisoning of allergic substances may also free the employee of all signs is usually an accumulative process. It and symptoms of lead poisoning. But takes time to produce a manifestation of imagine the surprise of that supposedly disease, but let any other substance cured person when years later, perhaps cause the disease, and the irritating food following some type of infectious disease may be of sufficient strength to mag or the excessive use of alcoholic bever nify its action. ages, he awakes to find that he suffers Alt cases of dermatitis cannot be the aches and pains and paralyses of an cured by eliminating offending foods, acute lead poisoning. As the body fluids but further investigation along these alter lead that it may be deposited, so lines may give us a clue with which to may those fluids attempt to de-lead the lessen (he loss of time from work and hoHv. and too ranirl nlwimfinn msv nrn. duce the original disease with all its di?. comforts. One can readily see, then, that in somt cases investigation of previous occupa tions is quite necessary to determine theoriginal contact with lead. Heating of molten lead causes a black scum-of lead suboxide to form on its surface, and the heat from the metal disburses the fine powder into the air. Hence, in the process of smelting ores such as zinc, copper and silver, mixed with lead, we find a rather high lead poisoning rate. Those engaged in the manufacture oi lead wire and cables, batteries, glass, pottery and rubber industries, plumbers and users of dry colors offer their share of lead poisoning cases. Probably the greatest source of lead, poisoning may be found among those who sandpaper, scrape, chip or burn iead paint, for the dust and fumes caused by those activities are rather rapid in their action. Such workers may become iocapadtated in a few days because the inhalation of lead dust causes the maxi mum amount of absorption into the blood stream in the minimum space of time. Cuxounnc: Chromium is a metal widely used as a foundation for colors, and dusts from its various salts may produce lesions of the skin and mucous membranes of the nose. Chromium plating by electrolysis may cause fumes which are similarly irritating. Although chromium poisoning does not usually cause death, the number of days of ab sence from work on account of --ncaparity which it causes is gradual-:- ,n' creasing. Othex Metals: The most effiricnl portals of entry of foreign substances into the body are the nose and in0UL The smaller the dust (the size of particles for example, the greater '> speed of absorption by the blood. from hot metals carry not only P015" but numerous minute _' i . . . * dust par111- _ if** *' mt; utwjt. ............ . electric cutting and welding. When men are so employed over a prolonged period of time, the constant inhalation of fumes and dust might pro duce symptoms of the metal upon which they work. In the shipbuilding trade, particularly in the construction of metal ships, we find occasional cases of metal- fume fever. ``Brass chills" and "spelter shakes" from zinc are names applied by the lay people to such diseases. The ter rific heat applied to some of our com mon metals and alloys by acetylene torches produces sufficient fumes to cause a temporary incapacity in 24 hours. Permanent disability from such causes is rare, however. Diseases Due to Dust Twenty-five per cent of all workers exposed to high concentrations of inor ganic dust are expected to develop changes within their lungs due to that agency. We are at a loss to explain why the other 7S per cent are not so affected. Mining, quarrying, foundry work, grinding, sandblasting, abrasive soap manufacturing, asbestos work, the mak ing of emery and carborundum products and many other occupations offer op portunities for employees to inhale mic roscopic dust particles and create a foundation for possible future inca pacity. We are interested particularly in those men who work with sandstone, quartz, flint, granite, and sand, because they expose themselves to silica, and the chemical changes between that dust and the body fluids, in the presence of tuber culosis, may and usually do lead to a fatal ending. It is safe to say, in light of our present knowledge, that the action of other in organic dusts is much, less virulent and incapacitating. That, however, does not allow us to lower the vigilant methods to improve dust control and protect em ployees, because all dusty occupations are potential trouble makers. Although the actions of various dusts differ within the body, the exposure to asbestos fibres, present in the weaving and grinding of dry asbestos material. offers another type of dust which may cause fatalities among workers. "riie organic dusts from cotton, silk, wool, tobacco, flour and similar sub stances are practically harmless. Such dusts rarely reach the lungs but may cause irritation of the windpipe and larger air tubes and result at the most in a mild bronchitis. mind, particularly when dealing with silicosis and nsbestosis, relates to the progression of such disease, s When changes occur within the lungs as a re sult of the presence of such dusts, nature forms scar tissue to heal such lesions but may fail to stop when the job is finished. As a result, the continuation of that healing process may lead to such structural changes within the lungs that partial or -total incapacity may follow months or years after the employee has been removed from his dusty occupa tion. Benzol-Benzene Benzol is a distillate of coal tar used extensively in industry. It is an essentrial ingredient in the manufacture of explosives. It is an excellent solvent for grease, oils and cements, and because of that property it is important in many phases of the rubber and cleaning indus tries. In the manufacture of shoes ben zol may be an ingredient of the dressing applied to the leather and of the cement which fastens the heels and soles. Not only in the shoe trade but in other branches of industry where employees work with gummy, sticky material, the workers soon learn of the solvent and cleansing action of this liquid and use it freely for that purpose upon them selves. The subsequent outbreak of skin afflictions may be the first indication of such unauthorized use. Benzol is extremely poisonous, enter ing either through the nose or mouth or absorbed through the skin. Its action within the body is varied and may pro duce a multitude of signs and symptoms. The bone marrow becomes affected which in turn alters the character of the blood; hemorrhages are common; it may cause death. The fumes from benzol are heavier than air and lie near the floor, which is an important point in the engineering problem of ventilation. The members of the benzene group are absorbed through the skin, and more cases of poisoning are found when men perspire than when their bodies are cool. Probably the answer to that is that the fumes may solidify as they cool and the powder may settle on the skin. The sweat on the body may dissolve this dust so that it is more readily absorbed through the increased surface blood supply. Chlorinated Hydrocarbons This group of petroleum derivatives lias been known to science for years hut the industrial field has been widely (j,s. tributed and most important. Led bv carbon tetrachloride and its chemicallv associated members, it has furnished in. ductry with refrigerants, excellent solvents for rubber, wax, oil and grease thinners for lacquers and a very f,'n< household necessity for the removal nf spots from clothes. Hospitals have been using it more and more for the removal of adhesive plaster.. Due to the non-flammability of car bon tetrachloride, it is used in fire ex tinguishers. The rapid evaporation pro duces fumes which may smother a small blaze, but we must not forget that ex cessive heat of the actual fire may bring about combustion sufficient to produce such by-products as hydrochloric acid and phosgene gas . Like its associated member, choloroform, it may produce sleep when inhaled by an individual, and only 1/3S0 of an ounce in a quart of air is necessary to produce such action. That thought must be remembered when .1 large quantity of those liquid products is spilled on the floor, perhaps accidentallv. Action should be started at once before the liquid gasifies, and employes should be notified to keep their heads up to avoid the low ceiling of gas. Chemists have developed and intro duced to industry many new products-, the basis of which is the chlorinated hy drocarbons. These derivatives of petro leum distillation are frequently combined with those from coa! tar to form valua ble chemical combinations. They have been placed on the market so rapidly that medical science has been unable to determine their physiological effect upon the health of man. We have known th.n some of these chemicals are capable ni creating changes in the liver, and <>niy recently in a city in Massachusetts one of these newer products caused the death of two employees and a battle to retain life among two others. Carbon Monoxide You remember the adage. "Wherr there is smoke, there is fire." We might add to that, "Where there is fire tluT>- >carbon monoxide." This odorless but poisonous gaf m;I> occur in any industry or in any home but the poorer the ventilation the better the chance of producing physical ir" capacity. Since the advent of the motor <-lf whose exhaust pipe may pour fortn -1' high as six per cent of carbon men"' ide, we are all exposed to that cos. lf ticularly in crowded cities. The a*/ (xukoenger car Uuetdicp auvui cubic feet per minute, and one can readily estimate the physical damage that may be done if such a motor is allowed to run within the doors of a poorly ven'jlated garage or shop. For tunately, serious cases of such poison ing are not common among those em ployed in public garages, but many em ployes are liltely to complain of head ache and faintness at the end of a day's work, especially in colder weather when doors and windows remain closed. In the steel indus'ry, where gas is used as the beating agency in the blast furnaces, care must be taken to provide proper ventilation. Within the mines, workers are warned to allow enough time following blasts for the escape of this gas. Infection The skin is a protective covering of the body against infection and is ex tremely efficient as long as it remain in tact, but allowing it to be broken or punc tured introduces bacteria, and a battle ensues between the offensive agencies of infection and the defensive powers of the body. The winner of such a struggle may determine the presence or absence of incapacity. Infections are common throughout industry, but two types are particularly prominent--infection re sulting from anthrax and infection among meat packers and fishermen. Many of our fur, hair or woolcovered animals may contract anthrax. The germs of that disease defy the ordinary methods of sterilization and may linger on hides, bristles or hairs for long periods of time. Tanners, wool sorters, and hair or bristle workers may introduce the anthrax spore beneath their skin and undergo much physical suffering and sometimes death. Infections are freqwntly found among meat and fish packers and those engaged in deep sea fishing;- Although death rarely occurs, the loss of fingers, hands and nasty septic wounds are the result. Summary I feel that the time has come when an employer must demand of a manufac turer the answers to two questions: 1. How will your product affect my bu'inoj ? 2. How will your product affect the health uf ray employees \ That employer is entitled to honest answers based upon sufficient chemical and physiological examinations of the questionable product. Too many lives have been lost or jeopardized by too little knowledge of a product's action .i------- ; / F e r r o $ i I i c o n, <A.. t Industrial Data Sheet D-Chem. 20 A. Problem 1. What are the hazards of ferrosilicon and what precautions are necessary in its use? B. Hazards 2. The principal hazard is that of poisoning by inhalation of the gases that may be given off, especially in the presence of moisture. C. Discussion 3. Ferrosilicon is prepared by melting iron ore or steel shavings with coal or coke and ganister or quartz at a temper ature of about 2,000 degrees centigrade (3,632 degrees Fahrenheit) in an elec tric furnace. In making steel, ferrosilicon is used for removing objectionable gases and oxides and also as an alloying dement. When alloyed with cast iron, it affects the carbides and renders the iron soft and gray. More concentrated silicon alloys are sometimes used in cer tain processes for making hydrogen gas and in the manufacture of explosives. 4. The hazard in connection with fer rosilicon results from very small percent ages of phosphorus together with other elements which may be present as im purities originating in the raw materials used. In the presence of moisture the phosphorus compounds react to form phosphorated hydrogen or phosphine. This is a gas which in sufficient quanti ties is decidedly poisonous. It has a strong and distinctive odor somewhat re sembling garlic so that its presence can be readily recognized; The stability of ferrosilicon depends upon its silicon con tent, grades below 48 percent and above 65 percent being entirely stable and ferrosilicon in these ranges does not give off any appreciable quantities of phosphine, even in the presence of moisture. It is, therefore, only in the intermediate range between 48 percent and 65 percent that there is any appre ciable hazard. Symptoms of Poisoning 5. When a person has breathed poison ous gases -liberated from ferrosilicon. the symptoms of poisoning usually de velop quite suddenly and are character ized by general and abdominal pains, nausea, vomiting, diarrhea, hemor rhages, loss- of consciousness, dilated pupils, cold clammy perspiration and coma. Cases of poisoning have been mistaken for cholera, gastro-enteritis. ptomaine poisoning, pneumonia and in fluenza. First Aid 6. When a person displays any symptoms of poisoning because of the inhalation of the poisonous gases lib erated by ferrosilicon, be should be promptly removed to the fresh air and, if conscious, be given a mild alkali drink. If unconscious, the prone pressure method of artificial respiration should be started immediately after the patient has been removed to the fresh air. in all cases of poisoning the services of a doctor should be promptly obtained. Precautions 7. Ferrosilicon should be stored away from such places as offices and work rooms or living quarters of any descrip tion. 8. All buildings in which ferrosilicon is stored should be well ventilated and dry. (See Note X.) Ordinarily, in an open factory building the natural venti lation through monitors in the roof or through windows is sufficient if the ferrosflicon is kept dry. 9. If men are required to handle wet ferrosilicon in a confined space, artificial ventilation should be provided. 10. In case phosphine has been al lowed to accumulate in a closely con fined space such as a closed room or box car, so that a strong odor of the gas i* noticeable, no one, unless he is wearing a suitable gas mask or fresh air hose mask, should be allowed to enter the room until it has been thoroughly vrn''lated.

Voyta Wrabztz, Chairman, Industrial ' Commissida of Wisconsin.- .- CHAIRMAN ELIASON: Last year, the pattern was' set for the meeting: this year.! If yon will.recall, there was a plat form adopted as follows: (1) .Promotion of safety to create a definite objective of labor; (2). Management .actively. should seek labor's cooperation;. (3) The basic responsibility for the safety program-must be accepted, by management: (4) The physical (condition , of the plant ts an es sential, factor in any, safety program; (S) Full cooperation'of organized labor with the National Safety Council is necessary to put across the best possible safety program! the top people in organized labor, to.carny out their responsibility on safety.' And now, Mr. Armstrong. 'v~- MR. ARMSTRONG: There shouldn't be any contusion about safety and the cooperation we should get between man agement and labor relating thereto; I don't think either-side should refuse to sit down and get. together on the subject that we a^e here to discuss this morning --the safety- of those within our plants. We have heard a great deal in the news papers about strikes. - We hear far too little about accidents. When we stop to look at the figures we find a tremendous number, of hours lost due to accidents, as ` compared with any other phase of lost ' time, strikes,- labor turnover, absenteeism, or anything else. From my experience, and)l only talk from my experience, and^I hope it- has not been nnusnal, we have been able to get along very nicely with labor,, and its safety question. Now, I give you briefly just a pattern of organization. I will let the balance of it go to the questions relating thereto. Before we: hear from our first speaker, I. should-like, to stress the importance of safety being accepted, by. top management. When Irsay.thaCl mean, from the chair man of v the. board, or the chief executive officer, right oh down.'/ If that isn't the case; I cannot see how a safety program No. 1: Supporting the plant manage ment is an executive committee. It is made up of the management of the plant, the president of the local and) the various divisional superintendents. Each year they set the policy with respect to the jobs to be done that year and with respect to the 273 1 Marine Section \/ Executive Committee 1944-1945 General Chairman--W.

In the measurement of the concentrations of dust that are present in air used for the ventilation of mines, or other working places, it is recognized that the dust is not uniformly dispersed in- the air. Also that' under the same atmospheric conditions widely different results may. .be obtained * by the use of different dust sampling instru ments, and by different methods of quanti-; with the tube vertical.' This means that air drawn from a horizontally moving, air stream must be deflected at right angles- to its ' original direction of flow., to. enter the tube opening.. The mothentnm ot the dust particles would then tend to continne them in morion past the tube opening; and thus reduce' the dust content of the sample vol ume. .. -j tation. In dust sampling work done by die To develop the effect of these conditions writers with impingers a number of sources upon dust sampling results, some tests were of error have been found to exist, and these made by taking dust samples from air mcrr- are here described for the benefits of others 'ing horizontally at different velodtiersimnl- engaged in similar work. taneously with two impingers, ooe having the ordinary vertical tube opening at right Is&pinger Sampling in a Flow of Air, angles to the, direction .of flow, .and; the In the collection of any volume of air for dust sampling purposes, it is essential that the number of dust particles in the sample volume be the same before and after collec tion. When the air is not in motion it may perhaps be assumed that this condition exists for sampling with impingers. However, other, being equipped with an elbow exten sion to bring the tube in line with the direc tion of flow. Two samples were also taken with restricted orifices placed at the elbow openings so as to make the velocity of air passing through the orifice the same as that of the main air stream. . 7 dust sampling in mines is often done in Dusty air. for thuTparpose was .obtained flows of air moving at fairly high velocity, by ^allowing a flow of dust, collected at a and similar conditions exist in ducts`Carry bog type' dost arrester, to fall at a short ing flows of air from dust collection hoods. horizontal distance away from .the <inlet of Although nothing like, exact measurement, a .blower.

Cafibntxoa of Impinger Tubes In the taking of number of dost samples at one time' with one instrument, it is nec essary tbat number' of impinger tubes be used^and variations in die volumes of air sampled by different tabes-under soch other wise identical conditions is a matter, of some importance. Variations in sample volume may occur because^ of differences in sire and shape of the tube, particularly the size of the orifice from whidr the air stream is impinged against the. bottom of the flask. For calibration ?b the tubes, it is, how ever, necessary to take into account'the soction pressure, or vacuum, induced , by the pump since in the case of compressed air operated ejectors, it seems impossible to obtain exact uniformity in the sire of the ejector orifice and this will cause some vari ations in the induced vacuum. In the case of thestandard tubes not much variation, is -shown hut in the case of mid get impmger tubes, there are appreciable differences.; \A nuTimmn variation of 23 per cent inShe volume of-air sampled may be noticed foi* tubes used in two different midget impingers and this is known to be mainly doe to variations m the sire of the orifice in the tubes supplied by the.manu facturer. .Midget impinger number one is equipped with a hand-operated, constant pressure pump and Midget impinger number two is equipped with a hand-operated pomp delivering constant volume at. constant speed. 356 33rd National Safety\Congress, 1944 Tabulated Na 3 Calibration Comparisons of Midget Impinger (Tubes Tube No. 1 2 3,, 4.

These are related mainly to the cleaning of the impinger tubes and counting cells. 1 q In the flow,of dusty air through an im pinger tube, the increased veloaty of air motion at the approach to the orifice causes a reduction of pressure which, with the accompanying cooling effect caused by evap oration of the collecting fluid in the flask, causes a lowering in the temperature of the air stream and ai consequent deposition of dust on the inside of the tube. Being difficult of access, this inside tube surface is often given only insufficient cleaning as by hand with the use of a pipe deaner or tapered brush. The following tabulation shows, for four different samples, the effect upon dust counts of placing^ poorly cleaned impinger tube in a flask with the usual quantity of collecting fluid and then briefly, shaking the flask by hand. A method of deaning the tubes, both standard and midget that has-given satis factory results includes a replaceable fibre brush held in a metal shaft that, is rotated by the motor of an dectric erasing marftinc, having a friction grip.

A common. defect in the Sedgewick-Rafter type is failure to closely seal the comers of vertical containing strips or walls, with the result that leakage or the evaporation of alcohol causes the formation of. air bubbles that interfere with counting. Corners of the cell are also difficult to dean. These defects are well recognized bat it is perhaps not so well recognized that appreciable variations in the depth of cells also occur. In the case 11 cells received from a supply .boose --jc variation in depth,1 as determined by microscope and micrometer was from 0.945 nun. to 1.195 nun. _ P ..

The coverslip is 38 nun, square and 1 nun. thick. Since all component parts are sep arated for washing and deaning, there are no surfaces that are not easily cleaned.- An essential piece of equipment for brushing, cell surfaces free of air-borne dust before'} filling with sample fluid is a good camels hair brush. An illustration of the effect upon dost counts of variations in the . depth of-cells is shown in Tabulation number five, which shows the counts obtained from two dif ferent portions of the same samples when counted in two different cells.
